We booked two rooms but when we arrived the owner had given them to some guests who filled also the last free room (they were 5, we were 3). The owner found us another accomodation, but with different services (i.e. we needed to have a wifi access, but the new B&B hadn't it). I can understand the equation: more guests = more money, but I think that this is misconduct.
I can't obviously evaluate services&rooms.
